Commit 27f5411a718c ("dm crypt: support using encrypted keys") extended
dm-crypt to allow use of "encrypted" keys along with "user" and "logon".

Along the same lines, teach dm-crypt to support "trusted" keys as well.

Is it possible to test run this with tmpfs? Would be a good test
target for Sumit's ARM-TEE trusted keys patches.

Also, I would hold merging *this* patch up until we are able to
test TEE trusted keys with TEE trusted keys.
